Used DD15 has spun rod and main but is repairable. Other than that the rest of the block and head are in good shape. Will come as you see in the pics and has not been opened up. No Flywheel but has front mount and rear housing. No oil pan. Injectors are intact and have not been messed with. Rocker box does not look to be cracked. Came out of a Freightliner Cascadia 2011.
